Abstract
We purified and sequenced the heat-stable enterotoxin produced by Citrobacter freundii. The toxin was detected during purification by reaction with monoclonal antibody to Escherichia coli heat-stable enterotoxin. The C. freundii toxin amino acid sequence was identical to that of the 18-amino-acid heat-stable enterotoxin (STa) produced by toxigenic E. coli.
摘要
我们纯化并测序了弗氏柠檬酸杆菌产生的热稳定肠毒素。在纯化过程中，通过与抗大肠杆菌热稳定肠毒素的单克隆抗体反应检测到了该毒素。弗氏柠檬酸杆菌毒素的氨基酸序列与产毒素大肠杆菌产生的18氨基酸热稳定肠毒素（STa）的序列相同。
